Mechanical Engineer FAQs
Mechanical engineering primarily deals with designing and analyzing mechanical systems and physical objects, focusing on principles like motion, energy, and force. Electrical engineering, on the other hand, focuses on electricity, electronics, and electromagnetism. While a mechanical engineer might design the physical components of a machine, an electrical engineer would design the circuits and power systems that make it run. Often, these two disciplines work closely together on complex projects.
A PE license is not always required, but it is highly valued and can be essential for certain roles, especially those involving public safety, such as civil or structural engineering. While many private-sector jobs don't require it, a PE license demonstrates a high level of competence and integrity. It can open doors to leadership roles and is often required for engineers who sign off on projects for public works.
